2011 Yamaha YBR125 0.1L Petrol · CP11 AAX

The vehicle presents a generally stable maintenance profile, though the most recent MOT history indicates a sudden shift from clean passes to mechanical failures. While the July 2025 test resulted in a pass at 28,152 miles, the immediate failure on 21 July 2025 at 28,142 miles highlights specific mechanical neglect. The tester flagged a stiff or notched steering head bearing and an incorrectly fitted rear drive chain horseshoe locking device. These faults suggest that while the motorcycle is currently roadworthy, recent upkeep of critical control and drivetrain components has been inconsistent. The mileage pattern shows very low usage for a 2011 model, averaging approximately 1,877 miles per year. There is a notable period of inactivity between the July 2024 test at 23,164 miles and the October 2020 test at 22,997 miles, where the vehicle covered only 167 miles in nearly four years. Such long periods of standing can lead to component degradation, such as perished seals or seized bearings, which aligns with the steering head bearing issue identified in the 2025 failure. The recent accumulation of roughly 5,000 miles between 2024 and 2025 shows a more regular usage pattern compared to previous years. A prospective buyer should conduct a thorough physical inspection of the steering assembly to ensure the head race bearings do not exhibit any further notchiness or resistance during turns. The drive chain and its associated locking mechanism require close scrutiny to confirm they meet manufacturer specifications and are not subject to improper installation. Given the 2016 advisories regarding worn rear tyres and low front brake pads, the current state of all consumables should be verified, as the low annual mileage often masks the effects of age-related rubber degradation and fluid contamination.
